Color transfer from a real sunflower to the sunflowers in the London version A The color bar representing all hues of yellow in the ROI corresponding to the flowers in the London version. This color corresponds to the leaves of the HC tree computed from the colors of all pixels in this ROI. We select the region (cluster) 454_yE in this color bar which contains some of the darkest yellow pixels. The pixels associated to this region are referred to as F454_A. B The color bar representing all hues of yellow in the flower ROI of SF1. We identify the cluster SF1_yG in this color bar that contains some of the brightest yellow. The pixels associated to this region are referred to as SF1_A C Pixels in the London version that belong to F454_A are highlighted in red D London version: before color transfer E London version: after color transfer
